oh my god what are hands
Imagine Kylo rolling cigarettes for Hux because he doesn't want Hux to dirty is fingers. Ever since Ben was a young boy he would roll cigarettes for Han when he was asked to. After learning that Hux smokes he's always wanted to roll a perfect cigarette for him and watch him smoke it. He walks in on Hux one day rolling his own, and insists he does it so Hux doesn't soil his fingers. Kylo feels he dirties everyone he's ever grown close to so he doesn't want Hux to dirty his hands even more.
